Appucation ined November 29, 1927. seien No. 236,513.

. This invention relates to rim locksand more particularly to a device for locking demountable rims uponthe wheels of automobiles to prevent unauthorized removal thereof.

An important object of the invention is to produce a device of this character', which may be relatively cheaply and at the same time durably and ethciently constructed.

A further object of the invention is to produce a device of this character which may be very easily secured to the tire rim, which will be neat in appearancek and 4durable, and

f efficient in service.

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and `wherein Figure 1 is a fragmentary side elevation of an automobile wheel felly and an applied tire, the rim embodying a lock constructed in accordance with my invention, the felly and rim being partially broken away; l

Figure 2 is a section on the line 2-2 of Figure 1;

Figure 3 is a section on the line 3-3 of Figure 2.

Referring now more particularly to the drawings, the numeral 10 generally designates the usual'channeled metal wheel felly, in the base 11 of which, in accordance with my invention, I form a single opening 12.'V

Through this opening, I direct a sleeve 13, the exterior of which is threaded at its inner or base engaging end for the reception of nuts 14 and 15, which are adapted to be ar-v ranged at the opposite side of the base to clamp the sleeve in position with relation thereto, while the sleeve is directed Hradially7 of the completed wheel. The nut 14, which is arranged upon the inner face of the base, should have its innermost face slightly spaced from the inner end of the sleeve to permit application to the threads of the sleeve of the threaded flange 16 of a dust cap 17. The inner nut 15 is adapted for the passage of a set-screw 18 which, engaging against the threadsof the sleeve, eectually prevents rotation of the nut with relation to the sleeve and'accordingly prevents removal of the sleeve by rotation applied to the inner end thereof. In the side wall of the sleeve are formed a longitudinally extending slot 19 and an openingy 20, the purpose of which will presently appear, while the outer end of the sleeve has an inwardly directed flange 21 delining a central opening 22.

Within the sleeve I arrange a lock barrel 23, the side wall of which has applied thereto setscrew 24, which operates in the slot 19 and accordingly permits longitudinal movement of the barrel while preventing rotation thereof. VThe rota-table locking part, ,i

generally designated at 25, operates a radiallyl extending bolt 26, which may be either withdrawn in the barrel or extended into the opening 2O in the side wall of the sleeve. 'if his locking part 2G aligns with the opening of the sleeve only when the barrel is at its outermost or locking position. The barrel has an axial extension 27 at its outery end, which is adapted to extend through the opening 22 defined by the iiange 21 of the sleeve and project into a socket 28 formed in the sleeve 29. Seating upon the iiange in the sleeve is a packing element 30 upon which,

through steel washer 31, abuts one end ofV 1 a spring 32, the opposite end of which engages the barrel and serves tonormallyforce the barrel inwardly from the locking position.

It will, of course, be-obvious that in applying 'afloclr of this character, the lock will be arranged at a point remote from the valve stem opening of the rim, so that between the lock and the valve stem opening, removal of the den'iountable rim and its tire is prevented. It will furthermore be obvious that a lock of this character is very easy of application since itis merely necessary to form a single opening in the tire Vrim for the passage of the sleeve. The nut 15 may then be placed upon the sleeve and adjusted, so that the inner end of the sleeve is placed in the proper position, at which time the inner end of the sleeve is passed through the opening and the nut 111 applied thereto to secure the same in position. lVith the rim applied to the felly, the removal of the lock casing is impossible and since the rim may be onlyv removed by an authorized person, loss of the j and modification without materially departing from the spirit of the invention, I do not limit myself to such specific structure except as hereinafter claimed.

I olaim:-

In combination with a Wheel felly having a channeh in its periphery, an opening formed in the base of the channel, a sleeve extended through said opening,` and having its exterior screw-threaded at its inner end,r nuts upon the sleeve engaging the felly at the hase of the channel and at the inner end of the felly to retain the sleeve in position, a

lock barrel longitudinally shiftahly mounted in the sleeve :1nd held against rotation with relation thereto, :i locking pertassociated With the barrel and adapted to engage in an opening in the sleeve in one position of the barrel and an axial projection upon the outer end of the barrel extendingI beyond the outer end of the sleeve When the barrel is in the last named position.

In testimony whereof I hereunto aix my signature.
